Abstract (en)

The present invention discloses a processing method of an event data stream, which is from a dynamic vision sensor, the method comprises steps of: acquiring inertial measurement parameters, which corresponds to one segment of the event data stream for generating one frame of image; determining attitude angle data based on the acquired inertial measurement parameters and calibration parameters of the dynamic vision sensor; generating a transformation matrix based on the determined attitude angle data; processing the one segment of the event data stream using the transformation matrix, to generate the processed event data stream. The present invention also discloses a corresponding computing apparatus.
